AMarshal and Vim

[Hugh Sasse Staff Elec Eng]

I've just been looking at AMarshal with the 20-SEP Vim-Ruby.
There's some cunning stuff going on with quotes, but it really
upsets the Syntax highlighter.  There are only a few files there,
but the amarshal.rb and the rubyexpression ones were particularly
challenging.  I note that many legal symbols don't show up as
symbols.  I might be able to fix that bit myself, the other stuff
is probably beyond me.  Anyway, it is a good test case.  You can
find it in the RAA...

         In haste,
         Hugh
